Shortcuts

Program functions are referred to as “shortcuts” in nano, such as saving, quitting, justifying, etc. The most common ones are listed at the bottom of the screen, but there are many more that aren’t. Note that nano does not use the Shift key in shortcuts. All shortcuts use lowercase letters and unmodified number keys, so Ctrl+G is NOT Ctrl+Shift+G.

Hit Ctrl+G to bring up the Help documentation and scroll down to see a list of valid shortcuts.

When you’re done looking at the list, hit Ctrl+X to exit help.
